, OF ELBERFELD, GERMAN Y, A COMPANY OF GERMANY BRAID AND LIKE WINDER Application filed June 27, 1930, Serial No. 464,359, and in Germany July 10, 1929.

This invention relates to a machine for winding braid or the like on cards or the like and of the kind wherein the feeding of the cards into the holders, the attachment of the braid to the card, the rotation of-the latter for winding the braid, the cutting of the braid and the deliveryof the wound card, are automatically effected.

The invention consists essentially in arranging the braidclamps and the shears for cutting the braid directly on the card holders, the ob ect being to obtain, within very nar row limits, a correctly measured length of eans are also provided for feeding the braid so as to place the last but one convolution in a diagonal position on the card as well as'means for pulling said diagonal convolution over the severed end of the braid so as to retain it in position.

Fig. 4 is a section on the line IV-IV of Fig. 1, seen in the direction of the arrow 1,

Fig. 5 is a front view of the card magazine, and

Fig. 6 is a section on the line V IV1 of Fig. 1, seen in the direction of the arrow 2.

The machine comprises three upright casings 1, 3 and 5 the two latter of which are mounted on and adjustable along an elongated bed frame 2. The casing 1 is secured to one. end of the frame 2 and carries one of the operating spindles 20, the other operating spindle 6 being mounted in thecasing 5 in alignment with the spindles 20. The casing 3 serves as a magazine for the cards or the like whereon the materialis to be wound and it is laterally oifset on the frame 2 and from the spindles, as shown in Fig. 6. The cards supported in the latter by a plate 11 which is carried by a cylindrical plunger 112 having weight reducing apertures 114. A- spring 115 surrounds the latter-and exerts upward pressure on the plate "11 so as to press the cards latter for breaking can be adjusted for various thicknesses of against a slide 53 which covers the top of the magazine and which moves under a rigid guide plate 52.

Mounted on the adjacent ends of the spindles 6 and 20 opposite the card magazine,

are two card holders 61 and 78 respectively. The slide 53 is reciprocated periodically and has a shoulder whereby the top card is engaged and pushed into slits in the holders 61 and 7 8 while the slits are in a horizontal position and in alignment with the slide. The spindles are fitted with pinions 22 which mesh with gear wheels 21 on a shaft 19 and receive motion from the latter for rotating the The shaft 19 receives motion from a shaft 13 through the medium of spur gears 16, 17 and 18, the gear 17 being an idle gear and mounted on a pivoted bracket 23 (Fig. 6) allowing the gear 16 to ing the ratio of the transmission. The shaft 13 carries a Maltese-cross 1 1 which co-operates with a pin wheel 12 for rotating the shaft, the pin wheel being mounted on a shaft 11 whichis rotated by a worm gear 9, 10.

The worm shaft receives motion from a suitable motor through the medium of speed re ducing gears 7 and S. The pin wheel 12 is continuously rotated and drives the shaft 13 and the spindles only during twelve fifteenths of each revolution. During the remainder of its revolution it engages the Maltese-cross with a segment 15 and maintains the spindles with the card holding slits in the horizontal position shown in In order to allow the stationary position of the card holders to be rectified after a change of gears, the pinion 18 is connected to its shaft 19 through the medium of a flange coupling 108, 110 (Fig. 2) and screw bolts 109, the latter being passed through segmental slots in the flanges so as to allow the shaft to be rotatably adjusted relative to the pinion.

The braid or the like is fed to the cards through a traverse guide 88 mounted on a slidable shaft 91 Fig. 6) The cover plate 90 of the guide restricts the passage through the purposes, and the plate the latter are at rest and while 60 spindles.

In case the braid knotted, the knots will be engaged between the'rod 9d and theroller 93 and turn theframe 96 so as to withdraw the support from the arm 100. The spring 99 can then actso as to stop the machine. The lever 101 is fitted with a handle whereby the mechanism position. 1 The guide plate 52 for the card feeding slide 53 is provided with brackets wherein the shafts 91, 95 and 97 are supported. The

structureis connected pivotally to the magazine and is held in position a locking rod '116 after the withdrawal of which the structure canbe tilted in order to allowthe magathe card. mounted v I with abutments the starting end of the braid V v while the latter is engaged by the abutments 82. The collar 76 is controlled by lever 7 5' I which, on being operated, first .advancesthe zine to be replenished with cards. 7

The cardh'lder 78 is provided with am for clamp ng for clamplng the starting end of the'braid to on the holder so as to bejrotated together with the latter, and a wedge-shaped collar 7 6 which alsoxrotates togetherwith the holder and'which is connected tothe slide by means of a coil spring 77. A double armed trolled by a spring83, carriesa fork provided 82 adapted ,to be applied to the card so as to clamp it to the holder and retain it in position. 7 The lever; also carries a resilient'finger 81 which is adapted to clamp against .the card slide and the'lever into operative position, and then, while compressing the spring: 77 bevelled surface engages the lever 80 with its andturnsthe lever in opposition to the spring 83 so as to apply the finger 81 to the braid andthe abutments 82 to'the card. Y

,j'A'similar arrangement of. slide and'collar isto be found on the card holder 61. In this case the slide'65 is fitted witha" pair of shears feathered on the shaft and con 3 on the latter shaft is connected collars 22 on; rods 37, v38, tively so as'to reciprocate the latter ncothe card tothe holder and also uch means comprise a slide 7 9 The rod 39 inclined ation throughithe medium of a spring 60 and 7 then, while compressing the spring, engages 1 the lever117 and turns it so as to operate the shears.-'-The lever also carries a resilient clamping finger Gt which, before the shears are operated, engages the braid so as to retain the severed end thereof on the card. The collar 59 carries a hook-ended. rod 66 the hook of which is first advanced by the collar and then retracted for pulling one of the braid convolutions over the severedend of the braid. Spring controlled pins 67 and 68 are employed in combination with, a cam 118 for retainingthe shears and the finger 66 in operative position, aga inst the action of a spring 69, until the finger has been withdrawn from under the braid convolution pulledover it by thehook 66. I

The collars 59 and 7 6, the traversed'mechvanism and the card feeding slide 53 are-operated by cams connected to a drum 28, the latter being secured to the shaft 11.. The cams 2 1, 25, 26 and 27 co-opera-te with levers 33, 35, 34 and. 36respectively which are mounted on shafts 29, 31, 30 and 32 and which engage 39' and 4:0 respecoperation with springs41.

The rod 37 is fitted with collars 412a where- .by'it controls a lever 43 and operates,by

means of the latter in combination witha hollow shaft l tanda pair of conical gear segmerits 45 and 46, a rock shaft 17; The latter transmits motion by means of conicalgear segments48 and 49 to a rockshaft 50-which is mounted on the rear wall of tfemagazine 3 and which is fitted with a lever arm-51.. The latter controls the slide 53 and'is operated at the right moment for feeding ajfresh card lever 80, mounted on the sllde and con- I and by means of conical gear segments 56 and 57 a'forked lever arm which controls the collar 59.3 1 y isfitted'with collars 420 where- 'by it controls aleverfl mounted on a vertical shaft '71 passing; through the" hollow shaft 4 1, and operatesby means ofsaid shaft 7and by means of. con cal gear segments 72 and 73a rock shaft 74, thelatter being fitted with a forked lever arm 5 which controls the collar 76. I 5

Therod 40 is fitted with collars 42d wherebyit controls a lever arm 8 1 mounted on an rock shaft 85. Another lever. arm

86 on ,the latter shaft engages the traverse guide 88 and reciprocates the latter.

The action is as follows:

While the card holders are maintained by the segment 15 and the Maltese-cross 14 with the card slits in the horizontal position as indicated in the drawings, and while the slide 79 is retracted by the cam 26, the slide 53 is operated for feeding a card 4 from the magazine 3 into the slits in the card holders 61 and 78. Then the card is in position in the holders, the rod 39 is released by the cam 25, and the slide 7 9 is then advanced, and the lever 80 is operated by the collar 7 6 so as to apply the finger 81 to the end of the braid and the abutment 82 to the card for securing both in position. Thereupon the Maltese cross 1a is engaged in succession by the pins of the wheel-12 and rotated by driving the spindles and winding the braid on the card, the traverse guide 88 being meanwhile operated by the cam 27 for distributing the braid convolutions over the card.

During the last but one revolution of the spindles, the traverse guide makes a rapid movement towards the card holder 61 so as to lay the braid diagonally across the card. After the last revolution of the card holders they are again stopped with the slits in a horizontal position, and the shears are thereupon advanced for cutting the braid. Before the shears are operated for cutting the braid, the latter is secured by the finger 64. As the collar 59 is retracted after the cutting of the braid, the hook 66 engages the diagonally laid braid portion and pulls it over the severed end of the braid so as to secure the latter'in position. Meanwhile the finger 64 is retracted from under the braid portion pulled across it. It is then raised and the shears are opened and retracted. The slide 79 is now retracted by the cam 26 so as to release the finger 81'from the braid and the card from the abutments 82 whereupon the slide 53 is operated so as to supply a fresh card which, on entering the slits, pushes the old card out of the holders on to a delivery chute 119. Meanwhile the traverse guide is shifted over towards the card holder 78 so that, on the slide 79 being restored by the cam 26 for securing the fresh card, the end of the braid can be caught by the finger 81. Thereupon the operation is repeated.

The number of braid convolutions and thus the length of braid wound on the card may be varied according to the thickness of the material and to requirements. In the arrangement shown, the gears 21 rotate the spindles at the ratio of 6:1 while the Maltesecross receives motion from the pin wheel 12 at a ratio of 3:1. The ratio between the gears 16 and 18 can be varied from 1 1 to 3: 1, which allows the winding of the cards to be varied from 18 to 54 convolutions.

The casing 5 can be adjusted along the bed frame 2 and along the shafts and the rods for admitting larger cards, and the casing 3 canalso be adjusted and exchanged. The cam 27 is exchangeable for varying the extent of the traverse movement according to requirements. The bed frame, the shafts and the rods may be made long enough to take a plurality ofsets of winding mechanisms all of which may be controlled from the same cams.
